Title: Wire cut electric discharge machine
Inventor: INOUE KIYOSHI
IPC: B23H7/10
Filed: 1987-01-28
Abstract: PURPOSE:To easily remove a machining chip or the like, accumulating in a machined groove, and to enable a machining speed to be improved, by providing a control circuit which controls a receiving device or a brake device so as to change the moving speed of a wire electrode to be increased and decreased by the fixed time interval. CONSTITUTION:A numerical control (NC) unit 14 supplies a control signal, which adjusts a speed to increase and decrease by the fixed time interval, to a receiving motor 7 controlled by a control power supply circuit 12, correspondingly repeating high and low speed controls for the predetermined time. Accordingly, a wire electrode 1, which moves running, repeatedly changes its moving speed to high and low speeds, but the wire electrode sets its low speed to about the speed of normal feed and high speed to the value of the normal speed or more. And for switching to the high and low speeds, the wire electrode, when it switches its speed to the high speed by the plate thickness of a workpiece 3, switches the speed by the time interval to an extent such that the wire electrode enables its point end to pass through the workpiece 3 from its upper to bottom. This switching time interval is input by an input device 15, in this way, a machine, enhancing a removal effect of a machining chip, accumulating in a machined groove, while improving circulation of machining fluid into a machined part, enables electric discharge machining to be stably performed with less generation of arcing and short-circuiting.

Title: Ringing choke converter apparatus and operating voltage range expansion method
Inventor: YASUKAWA KUNIAKI
IPC: H02M3/28
Filed: 1995-02-08
Abstract: PURPOSE: To output a secondary-side voltage over a wide range without lowering steady efficiency by a method wherein the resistance value of a first start resistor is made small in a period in which the voltage of a secondary winding of a transformer is not established. CONSTITUTION: The resistance value of a second start resistor RS1 is set in such a way that a parallel combined resistance value which is composed of the resistance value for the second start resistor and of the resistance value of a first start resistor RS is lower than the resistance value of the resistor RS. A switch SW1 is controlled to turn on in a period in which the second start resistor RS1 and the voltage of a secondary winding NS of a transformer 1 are not established across the start resistor RS in order to change over the value for the start resistor RS. Thereby, the resistance value of a start resistor which determines the oscillation level can be made smaller than the resistance value in a period in which the voltage of the secondary winding of a transformer for a ringing choke converter apparatus is not established.  Consequently, the operating range of the power supply can be expanded without extremely increasing the loss due to the start resistor which determines the oscillation level.

Filed: 1995-02-08
Abstract: PURPOSE: To reduce a circuit scale by converting a phase of an error signal obtained from a demodulation signal and an identification signal based on phase information to reduce a delay time of a control loop. CONSTITUTION: Waveform ROMs 8-1, 8-2 generate a waveform used to rotate a signal phase at a phase compensation circuit 3 by using a carrier phase control signal from a phase accumulator 9. An error detection circuit 12 obtains a gain error based on correlation between a demodulation signal and an identification signal and generates an offset error signal by applying phave conversion to an error signal obtained from the demodulation signal and the identification signal based on phase information. In this case, a time difference between the demodulation signal and a carrier phase control signal caused by an output delay time of the phase compensation circuit 3 and an equalizer 4 is adjusted by using a delay circuit 6.  Thus, I, Q channel signals are simply extracted without phase inversion compensation to an amplitude error component and offset component, a delay time of a control loop is reduced and the circuit scale is decreased.

Abstract: PURPOSE:To reduce the size of a polychromatic developing device by using one developing roll in common to respective color developing processes, and gathering respective color developer supply means and recovery means at one place separately from the developing roll part. CONSTITUTION:A toner accumulated in a black toner bottle 29 is supplied to a developing bottle 25 by a proper quantity through a toner dispenser 28. A developer supply auger 8 rotates by being energized by a developer supply auger driving device 26 to send toner and magnetic carriers to the developing roll 3 as a two-component developer while mixing both. This developer falls from an opening 12 onto the surface of the developing roll 3 to develop the image on the photosensitive drum 5 by the arrow-directional rotation of a rotary sleeve 6. The excessive toner on the surface of the developing roll 3 falls onto a back developer recovery auger 14. The developing roll 3 is cleaned up by a scraper 24 and foreign matters fall onto an auger 21. Development with a red developer is performed similarly and the residual developer falls on an auger 15 through a recovery blade 20. Thus, the device is reduced in size.
